TIIULLION COLUMN.

To all 'whom it may concer/a:

Be it known that I, BERNARD T. Mnsxnn, a citizen of the United States, residing at Saint Louis, Missouri, have invented a certain new and useful Improvement in'Mullion Columns, of which the following isla full, clear, and exact description, suchas will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of 4this application. j

My invention relates to building construction and particularly to such construction as utilizes steel sash for the windows or doors, a comparatively recent development which has been widely introduced in industrial buildings and is beingused morey and more in all kinds of buildings.

My invention consists in the provision of. improved means for unitingadjacentsteel sash and to be used in place of mullions and,l

transoms of stone, yterra cotta,cast iron, brick, wood, or built-up structuralsteel, all

of which are comparatively expensive to pro` duce, usuallyoccupy an excessive portion of the window opening, and are often difficultto make weather-proof. n f

rIhe object of my invention is to provide a one-piece steel mullion or transomv adapted to combine adjacent window sash'ofcthe common structural T-bar type, 'or other flanged sash section, thereby eliminating the neces-` sity of eld assembly of a plurality of structural transom or mullionparts, as well as eliminating the undesirable features above referred to attendant upon the other types of construction heretofore used.

Another object of my invention is to provide a one-piece mullion or transom member which may be assembled with window sash after the latter are in position, thereby eliminating the handling as a unit of a'plurality of sash. I accomplish this object byproviding a groove in the member extending from end to end thereof and adapted to receive endwise the projecting flanges of the sash T-bars.

In the accompanying drawings illustrating a selected embodiment of my invention- 'Figure l is an elevation of a wall in which are set a plurality of steel sash united by my improved mullion columns.

Figure 2 is a transverse section through one of the mullions and thefadjacent portions of the" steel sash.` y

Figure 3 is an isometricview, sectioned in part, of my mullion and two adjacent sash T-bars. r

Seated on `a sill l of a brick wall are the `steel sash 2, each including upright side one flange of each upright T-bar member projects beyondthe window and towardthe adjacent window. j

There is always asubstantial space between adjacent windows forvan intermediate column which extends from sill to lintel and the substance ofxmyA invention as here illus trated is. the provisionl of a Vcolumn or mullion-formed of a single steel plate presser into lthe section, bestshown in Figure 2, ink which an outwardly facing mullionforming surface 6 isv kformed from the center` of the plate with ysuitable flanges extending rearwardly therefromto the/rear of the windowy sash but grooved intermediate their front f and back at 8 to formrecesses 4adapted to receive flanges 5 on the window'sash.

rIhe outer face ofthe mullion'column'may be curved, f angular, jfluted, y,or otherwise shaped for various decorativeY effects` but ypreferably is of constant cross section from vided thefull length of the window and mullion column which will be more effective for excluding moisture from entering between the front of T-bar 4 and the adjacent edge of the mullion than a riveted Ijoint whichinvariably results in gaps at intervals between the riveted members.

An additional advantage of this construction is that the parts may expand and contract without any strain either in themselves or on connecting bolts or rivets heretofore 'contact which exceeds that afforded by built-up structures previously used.

The use of mullions of this type affords considerable economy in the assembly of the devices in the field as the mullion may be placed above and between two adjacent sash and then driven into its final position, or the sash may be inclined toward each other like a k'V and their iianges vinserted into the mullion recesses and the mullion and the inclined edges of the sash pushed back to the final straight line position.'

Vhere mullions of unusual length are required, it may be desirable to reinforce them intermediate their sides and this may be done by means of a structural member such as indicated at 9 'in Figure 3. This element could be added'in the shop before the mullion is sent to rthe field and consequently is adapted to economical riveting or spotwelding construction.

Obviously, the panel section of the mullion may be varied in Vwidth and shape to accommodate different width of windowopenings and produce various architectural effects without vchanging the sash from certain standard sizes or varying the sash engaging fianges. I/Vhile my drawing illusyments may be accommodated by the provision of suitable grooves or recesses in the -mullion columns, and other details of my invention may be modified without departing from the spirit thereof as expressed in the following claims.

T. claim:

1. In combination, a metal sash element comprising` a multi-flanged structural shape, and ainetal sash engaging member having a side contour which parallels at least two of the flanges of said element and embraces opposite sides of at least one of the flanges of said element.

2. In combination, two sashes having opposed side edges of uniform contour from end to end, and a one-piece pressed steel member connecting said sashes and having integral reenforcing sides provided with longitudinally extending grooves fitting over the side edges of said sashes.

3. In combination, two adjacent sashes eachhaving a side formed of a structural T- bar with one iiange extending outwardly fromthe sash in the plane thereof, and

means for uniting the sashes comprising a pressed steel member having reinforcing flanges which are grooved throughout their length and are adapted to receive the projecting fianges of said T-bars lengthwise.

4. In combination, a metal sash having a projecting flange, and amullion or transom comprising a sheet of. metal bent into a U- shape, a leg of the U being bent inwardly and outwardly t-oreceive and grip said ange. f

5. lIn combination, a sash element consisting of a T-bar with one lflange projecting outwardly of the sash in the plane thereof andanother flange projecting transversely of the `sash plane, and a sash connecting member consisting of aplate having a porgroove to receive said first-mentioned sash j flange and then rearwardly along said second-mentioned sash flange.

In testimony whereof I hereunto affix my signature vthis ninth dayL of November, 1922.

BERNARD T. MESKER.
